Solutions to put an end to China's air pollution crisis

We all know China has a severe air pollution problem, particularly in big cities such as Beijing. But what can - or dare we say, must - be done about it? The most basic solution for air pollution is to end its root causes: quit coal and move away from fossil fuels, replacing them with clean, renewable energy.

1. There must be clear, progressive and absolute limits on coal consumption that are placed on entire regions – a coal cap, to effectively restrain the rapid growth of coal consumption.

2. Severe regional pollution cannot be tackled as fragmented cities. Cities in the Beijing region, Yangtze River Delta and Pearl River Delta should formulate legally binding and regional coordinated plans to ensure air quality and propose clear timelines to reach national air quality standards, especially on PM2.5.

3. These regions should also introduce effective policy instruments to curb the rapid growth of the number of vehicles on the roads.

4. A hike in pollution discharging charges and strengthened supervision efforts could help make illegal discharges unaffordable.

5. Local governments should actively advocate eco-friendly lifestyles, and welcome public participation in improving urban air quality.
